My local pool company is just completing a new liner install for me. Everything looks great, except one corner (it's an oval pool, so not really corner but you get what I mean) of the shallow end appears to be stretched way to tight. The decorative band around the top looks stretched, and the border is 1.25" closer to the water in that location than anywhere else in the pool. I stopped filling it, but it was too dark to take pictures. I called, and they said it's fine, but I don't want problems down the road. Any thoughts?
